The analysis of the electrocardiographic patterns, as well as the vectorial study of the cardiac potentials during repeated episodes of ventricular \"anarchy\" induced in more than forty animals, showed the following data: 1. following electric shock, ventricular paroxysms appear, featuring paroxysmal tachycardia, typical or impure flutter, tachycardia--either \"torsade de pointe\" or \"spindle\" type, and typical ventricular fibrillation. Such different electrocardiographic patterns represent evolutive stages of electric activity disorganization, leading to a complete ventricular \"anarchy\". Such steps may reverse when reorganization of the electric activity and spontaneous defibrillation occur; 2. an attempt can be made at present to classify ventricualr paroxysms, thus eleminating semeiotic and semantic errors, still present in the literature, and providing a standardization of both nomenclature and electrocardiographic interpretation; 3. during fibrillation, the mean ventricular rate decays, featuring an exponential curve. This phenomenon accounts for a metabolic depletion of the myocardium: the higher the number of fibrillation episodes previously induced and subsided (either spontaneously or not) in the same animal, the faster the course of the phenomenon; 4. the vectorial analysis of the fibrillation potentials and, particularly, the graphic construction of \"depolarization\" and \"repolarization\" vectorcardiograms, in the differenttypes or variants of ventricular paroxysms, show that the basic mechanisms leading to ventricular electric activity disgregation are the multiple re-entry and the irregular spreading of the activation front; 5. on the basis of the acquired data, the authors believe that the \"circus movement\" theory (Wiggers) is still the most suitable for explaining the onset and the evolution of ventricualr fibrillation.","PeriodicalId":76102,"journal":{"name":"Lavoro umano","volume":"27 3","pages":"65-94"},"PeriodicalIF":0.0,"publicationDate":"1975-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12329960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A longitudinal electromyographic study (author's transl)].","authors":"G Giuliano, O Ronchi, L Rossi, L Focardi","doi":"","DOIUrl":"","url":null,"abstract":"A longitudinal electromyographic study was carried out on fifteen shoe-industry workers (one man and fourteen women) affected with toxic polyneuropathy. The mean values of age, duration of exposure and lenght of the follow-up period were 23.2 years, 4.2 years and 12.2 months, respectively. Twelve subjects (80%) had a sensory-motor involvement of both upper and lower limbs; in the remainder, only the latter were affected. From a clinical standpoint, the polyneuropathy was classified as mild in seven subjects (46.6%), moderate in four (26.7%) and severe in four. On the basis of electromyographic criteria (maximal motor nerve conduction velocity; features of voluntary contraction tracings; existence of spontaneous activity recorded in different points of the same muscle), the polyneuropathy could be defined as mild in two patients (13.3%), moderate in three (20%) and severe in 10 (66.7%). In eight subjects (53.3%) the electromyographic abnormalities disappeared completely, through a gradual improvement in six and alternative phases of improvement and worsening in two. As for the remainder patients (7, viz. 46.6%), improvement and worsening in two. As for the remainder patients (7, viz. 46.6%), four showed a reduction of their electromyographic abnormalities, whereas no significant changes occurred in the last three. The obtained results are discussed and the following conclusions drawn: 1. the lower limbs are mostly affected, both clinically and electromyographically; 2. the clinical symptoms do not parallel the electromyographic findings; 3. the course of the disease appears to be independent of the initial electromyographic pattern; 4. recovery appears to occur in most instances within approximately eighteen months since the onset of symptoms, generally without significant residual deficit. Finally, the role of electromyography in the diagnosis and the follow-up study of the observed toxic polyneuropathy is underlined.","PeriodicalId":76102,"journal":{"name":"Lavoro umano","volume":"27 2","pages":"35-41"},"PeriodicalIF":0.0,"publicationDate":"1975-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12403223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patients' age ranged from 30 to 57 years; the time they worked as vibrating tool operators varied from 5 to 36 years; the duration of symptoms ranged from 3 months to 10 years. The mean values were 46.1, 20.9 and 3.7 years, respectively. Seventy-four subjects (91.3%) complained of Raynaud's-like phenomenon, which in 36 (44.4%) of them was elicited too, although partially, by provocative tests (cold exposure). Angiography was carried out under general anaesthesia maintained with halothane. Bilateral angiograms were available in 61 instances; in the remainder, only either right or left angiograms could be obtained. In all the subjects examined arteriographic lesions were found, mainly represented by organic stenoses and occlusions. The prevalance of such lesions was minimal at the level of the forearm arteries, and maximal at the level of the digital arteries. The 2nd finger, bilaterally, was the most frequently involved; the index finger on either side and the middle one on the right side were the most involved as to severity and extent of lesions. The 1st finger, however, was quite frequently involved too. No definite relationship between prevalance, severity and extent of arterial lesions, on one hand, and some history, clinical and functional parameters (such as age, vibrating tool usage time, smoking habit, hand arterial pattern, pulmonary silicosis, instrumental findings and Raynaud's-like phenomenon), on the other hand, could be established. As to Raynaud's-like phenomenon, it is hypothesized that such a finding could be, at least in part of cases, subsequent to the previous development of organic lesions in the digital arteries.","PeriodicalId":76102,"journal":{"name":"Lavoro umano","volume":"26 6","pages":"161-97"},"PeriodicalIF":0.0,"publicationDate":"1974-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15574598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
